This herbaceous plant is conspicuous and interesting from 

 the clusters of yellow flowers, rendered more showy by the 

 dark spots, which serve to give brilliancy to the other parts. 

 In addition to the contrast of the colours in this, which distin- 

 guishes it from other species of the genus, there exists a 

 marked peculiarity in the style of flowering. In this, the flow- 

 ers appear in a close cluster forming a sort of raceme, while 

 in the other species they are more scattered. Though they 

 are of shorter- duration than many others, yet as they all ap- 

 pear nearly at the same time, they are when in flower de- 

 cidedly the most conspicuous of the genus : they are in their 

 greatest beauty and perfection towards the end of April, and 

 continue at least a month. As this species does not readily 

 perfect its seeds here, and is increased but sparingly from the 

 roots, it is on this account much admired and cherished in 

 places where it is cultivated. Nearly all the species in this 

 genus are humble in gi'owth, rarely exceeding a foot in height, 

 and many are much less. This species attains the height of 

 about one foot, and thrives well in a border of light but rich 

 vegetable mould. It is a native of Siberia, and was introduced 

 in 1783. This specimen was figured from Messrs. Malcolm 

 and Gray's Nursery, Kensington.
